14-3-3 proteins function in the initiation and elongation steps of DNA replication in<i>Saccharomyces cerevisiae</i>
Bibliographic record
Abstract
14-3-3s are highly conserved abundant eukaryotic proteins essential for viability, at least in lower eukaryotes. We previously showed that they associate with mammalian and yeast replication origins in a cell-cycle-dependent manner, and are involved in the initiation of DNA replication. Here, we present evidence that 14-3-3 proteins are novel regulators of the initiation and elongation steps of DNA replication in Saccharomyces cerevisiae. The results show that the Bmh2 protein, one of the two 14-3-3 homologues in S. cerevisiae, interacts with Mcm2 and Orc2 proteins, binds to ARS1 maximally at the G1 phase, is essential for plasmid stability, and is required for normal S-phase entry and progression. Furthermore, during G1 phase, the Bmh2 protein is required for the association of MCM proteins with chromatin and their maintenance at replication origins. The results reveal that 14-3-3 proteins function as essential factors for the assembly and maintenance of the pre-replication complex during G1 phase.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
